we also produced self PWM for ADC wave form testing. when we stop transmission, we will get good waveform out, but when we starting transmission, output waveform shape is...
Dear Support,
I have some troubles with the Evaluation Kit for nRF51822 :
I use the broad as a central role with S120_nrf51822_1.0.0_softdevice.hex and example...
Suppose a nRF9E5 transmitter is set for continuous transmission on a channel.
A nRF9E5 receiver listening on that channel:
finds carrier and sets CD
finds address...
I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...
I am try this at nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard

application note nAN-034 describes two alternatives for production testing an application using the nRF51822. One method is using a commercial tester (MT8852) and the other...
I need to send data PIR motion detector sensor to the master controller in my motion detector network.
Can I get away with just one of the nrf51 chips and my PIR sensor...
We're trying to decide at what voltage we should run our nRF51822 on the next revision of our board. To date we've been doing fine at 1.8V. The current drawn on a 3.7V lithium...
hi, i made ble app including bootloader using nRF51822 (s110), sdk 6.1.0
when i use sd_nvic_SystemReset() function in app, it erase app's pstorage.
But i want to preserve...
Hi,
I use S120 as central device and I need to handle multiple connections.
However S120 works quite unclear to me.
If S120 doesn't reply to BLE_GAP_EVT_CONN_PARAM_UPDATE_REQUEST...
Hello ,
I am trying to develop an application using the S130 soft device using Keil MDK v5 Lite. I have came to know that it is not possible to generate a code size greater...
I've run into a problem using the provided spi master code.
I get the following error message from Keil
spi_master.c(381): error: #1059-D: an entity with an internal...
Hi
I want to run the ble_proximity template on micro blend (Readbear lab). But I can't make it to work. I have uploaded the code to the board and using the nRF Proximity...
Hi all, I have followed the steps described

hello,
please find main.c file of code and how to add the MAC address to the ble_app_hrs sample code
that was provided in the samples directory of the SDK.
Can you...
hi,
I am trying to develop a network of ble devices.i want nrf51822 to function as a master and slave( not necessarily simultaneous). For that i need to develop a custom...
Hello,
Firstly, I just begun with BLE and I am trying to program nrf51822 to read the sensor data through TWI (I2C) connection and send this reading to the central device...
I have tested the ble_app_proximity sample firmware on nRF51822 eval kit and also on my custom board.
Everything, regarding the used services seems to work as intended. However...
We have an application in which it would be nice to change the supply voltage for our Nordic module (nRF51822 running the Soft Device) depending on which other modules on...
